Launched in 2006, the Ford S-Max is an elegant and versatile MPV that has won over families with its blend of comfort and performance. Across two generations, its gearbox has evolved alongside the Duratorq, EcoBoost and EcoBlue engine ranges. This guide covers everything you need to know about the Ford S-Max gearbox and how to keep it in top condition.
S-Max Gearbox Options
From the first generation, Ford matched its gearboxes to the engines on offer: five-speed MTX-75 manuals, six-speed MMT6 or M66 units — the latter typically paired with the more powerful diesels. The six-speed PowerShift dual-clutch automatic was available as an option, praised for its smooth gear changes. From 2015, the Getrag 6MTT250 six-speed manual accompanied the EcoBlue and EcoBoost engines, while the Aisin-built eight-speed 8F35 automatic was fitted to later versions.
Maintaining Your S-Max Gearbox
Checking the transmission oil level should be your first priority — not too low, not too high. If it is low, always verify the correct specification before topping up. Regular oil changes, roughly every 60,000 kilometres, prevent sludge build-up, and replacing clogged filters completes the service. A periodic look underneath the car will also help you spot any leaks early.
Signs of a Worn Gearbox
Unusual noises, a slipping sensation, difficulty selecting gears, or oil on the ground all point to a problem. The earlier you diagnose it, the simpler the fix.
Repair or Exchange?
Depending on the fault, a targeted repair may restore normal operation. Where wear is extensive — particularly on a PowerShift or 8F35 — an exchange gearbox replaces the unit with a reconditioned and tested assembly, giving your family S-Max a reliable new lease of life.
How the Exchange Process Works
The principle is straightforward: your original gearbox is removed and replaced with a unit of the same reference, reconditioned beforehand in our workshop. Every gearbox received is fully stripped down; its bearings, synchromesh rings and worn seals are replaced, then the whole assembly is rebuilt and tested before dispatch. This approach delivers near-new performance for your Ford S-Max, while supporting a more responsible approach to reuse compared with buying a brand-new part.
Why the Gearbox Matters
The gearbox matches engine speed to wheel speed — without it, pulling away, accelerating or maintaining a steady pace would be impossible. That alone shows just how critical this component is on your Ford S-Max. Neglect it and you risk the vehicle being completely immobilised; look after it and you are guaranteed smooth power delivery and safe driving every day.

Frequently Asked Questions
Which automatic gearbox is fitted to the later S-Max?
The eight-speed 8F35, built by Aisin, which replaced the six-speed PowerShift used in earlier versions.
How often should the gearbox oil be changed?
Approximately every 60,000 kilometres — and remember to replace the filters if they are heavily clogged.
Can the PowerShift gearbox be reconditioned?
Yes: the exchange process allows a worn PowerShift to be replaced with a fully reconditioned and tested unit.
How can I extend the life of my gearbox?
Drive smoothly, stick to the recommended transmission oil change intervals, and address any symptoms promptly. On your Ford S-Max, these simple habits reduce wear on the synchromesh rings, bearings and clutch, and push back the need for a major repair.
